I've been charged for 750 RUR (~ 11 EUR) after I clicked to "Upgrade to Pro" in Android application (v 4.4.9) but nothing changed neither in application (eg connecting to Evernote account failed with error message about this option is only available in Pro) nor in web/desktop version (this feature is also unavailable for the same reason).

I'd like to refund my money back or enable Pro version for my account. Thank you!
